Mold Breakerin Pokémon Polished Crystal

Mold Breaker is an ability that allows the user to ignore the abilities of other Pokémon when using moves. This means that if the opponent has an ability that would normally prevent or alter the effects of a move, Mold Breaker will bypass that ability and allow the move to function as intended. This is basically an override of any ability that would interfere with the user's moves.
